Because of the low grid frequency the time-variant control margin is especially limited. To reduce the demand on the converter control in case of load changes, the DC-load current is predicted by a parameter-dependent fourth-order time-delay element. This paper gives a short introduction to the test bench used for railway grid-interaction analysis. Furthermore the stator-flux-based Indirect Stator-Quantities Control (ISC) of induction machines as well as the derivation of the dynamic torque response and the resulting DC-load current are described.

The first converter works as a quasi-square waveform inverter with the main objective of injecting the energy produced by the photovoltaic generation system. The second converter acts as an active power filter with the objective that the current that flows from or to the grid is sinusoidal. The presented power injection system will be able to achieve a sinusoidal current even when a non-linear load is connected to the same point of common coupling. The performance of the proposed system, including the maximum power point tracking algorithm, is evaluated through simulation.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130092949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power supplies with hysteretic modulators exhibit superior dynamic performance and help reduce the number of output capacitors without sacrificing transient response. The synthetic ripple modulator (SRM) allows proper hysteretic operation even with a small and corrupted output voltage ripple. This paper discusses a dynamic optimization technique for the SRM, which enables the voltage regulator module (VRM) to get back within regulation in the least amount of time with minimum number of output capacitors. The design methodology and corresponding equations are derived and verified with a design example. Experimental validation on a 1.8 V/15 A module demonstrates the effectiveness of the technique with a maximum excursion time of 5 µs above the static regulation limits.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122958404","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We focus on the problem of differentiating two types of transients: short-duration (impulsive transients) and long-duration (oscillatory transients).

In the majority of cases all frequency components except the odd multiples of the fundamental oscillation of the grid voltage are strictly limited. Hence all advanced control schemes are operating grid-synchronised. Because these control schemes additionally need accurate information of the actual grid voltage often a combination of Phase-Locked Loop (PLL) and Discrete Fourier Transform (DFT) is used. In railway-grid applications there are special requirements to the transient response time of the synchronisation. In this paper the transient response time is notably reduced by using a sophisticated feed-forward control. Based on a brief introduction of the DFT this feed-forward control is derived in detail. Simulation results verify the excellent operation of the PLL and DFT combination even if the line voltage is disturbed by stationary and dynamic grid intrusions or pantograph arcing.","PeriodicalId":272748,"journal":{"name":"2009 Compatibility and Power Electronics","volume":"1 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117228253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
